It was a joke, dude.
An extreme right-wing conservative talk-show host first is a drug addict, and then gets caught with an illegal prescription drug - Viagara, of course! And on a fishing trip with the guys! Have you ever heard of irony?
Yes, I am pro-homosexual. That doesn't mean I wouldn't say anything if a big anti-gay person turned out to be gay. It's hypocritical to be against something when you are taking part in it yourself, whether it's drugs, homosexuality, prostitutes, child molestation, etc.
Actually, my point was to point out the irony of the situation, which was crystal clear from the first drug charges. He's a criminal, and people say he's the victim. My secondary point was, yes, to make fun of him. So what? All he does every show is attack and slander "libs." Where's the harm in making a little fun of him when he gets in trouble with the law?
